Corrosion Monitoring of Reinforced Concrete Structures

Corrosion Monitoring of Reinforced Concrete Structures

A proper test plan should take into account the following considerations:

  1. Exposure condition (Access to moisture, oxygen, exposed to de-icing salts, other chemicals, carbon dioxide);
  2. Geometry of the structures and components;
  3. Access to structural and non-structural components;
  4. Dimension and scale of the area under investigation;
  5. Importance of the element, etc.

The following inspection procedures are widely used during a routine corrosion monitoring program:

Chain Drag Delamination Survey
Chain dragging is widely used to detect delamination in concrete bridge decks. The concept behind this very simple method is the unique hollow sound that is made by dragging chain across the delaminated surface. The test is used to identify potentially delaminated areas on the deck slab.
The practice is difficult when vehicles are moving over the deck, and distinguishing the hollow sound becomes difficult.
The main disadvantage of the chain dragging method is that they can only provide results if the defect and deterioration are in well advanced stages. Early diagnosis of damage mechanism is not possible using this technique. Application of the method is somewhat difficult during heavy traffic.

  • Grand Egyptian Museum, Giza

The Grand Egyptian Museum has been described as the largest archaeological museum in the world. The building is shaped like a chamfered triangle and sits on a site two kilometres west of the pyramids. The building’s north and south walls line up directly with the Great Pyramid of Khufu and the Pyramid of Menkaure. The front facade of the museum will feature a translucent stone wall, made of alabaster. Inside the main entrance is a large atrium, where large statues will be exhibited.

  • 3 World Trade Center, New York

3 World Trade Center is a skyscraper being built as part of the rebuilding of the World Trade Center site in Lower Manhattan, New York City. The building will have a height of 329m with 80 stories.
3 WTC has a load-sharing system of diamond-shaped bracing, which helps to articulate the building’s east-west configuration. This allows unimpeded 360-degree panoramic views of New York.
